The cellular characterization of every tumor is essential to understand oncological mechanisms. At different levels and with complementary methods, Institut Curie provides approaches to study molecules, proteins, organelles and cells in normal or pathological conditions, in the whole tissue or at a single cell level.

Single cells analysis

Single cell platform activities are based on droplet-based-microfluidics. This technology consists in compartmentalizing a sample in droplets at less than a cell per compartment/droplet. Biological analyses are thus individual at the single cell level. This technology dramatically reduces assay trials time, reactions volume (up to a million times compared to conventional tubes or plates assays) and costs.

Another advantage of individualizing reactions at the single cell level is to take cell diversity into account. Indeed, the very high sensitivity of the analyses in droplets allows analysing both the cells majority and the few rare cells of the sample.

Key Information:

  • 10X Genomics Chromium 10X for ready for use Single Cell RNA Sequencing experiments
  • The inDrop System instrument of 1cellBio to do Single Cell RNA sequencing experiments
  • An evolutionary microfluidic station

Flow cytometry

Flow cytometry platform offers a multiparametric analysis of individual cancerous cells in suspension, by quantifying multiple markers on cells coming from your project, with the option of simultaneously sorting sub-populations of interest. Our technology also allows the in-depth analysis of the tumour microenvironment. We are able to advice you on cell preparation and choice of fluorochromes and offer a full support for data acquisition and analysis. Software training (Cell QuestTM and FlowjoTM)

Key Information:

  • FACSAria III has 4 lasers (488nm, 561nm, 633nm and 355nm), which can acquire 14 fluorescence and 2 scatter parameters
  • One self-service AutoMACS magnetic bead-based cell sorter
  • One Luminex analyze
